introduction: our aim was compare of two types of lithotripter include holmium: yag laser and pneumatic one in transurethral ureterolithotripsy (tul) for the management of ureteral calculi ≥1 cm. methods: 112 patients with ureteral calculi more than 1 cm were selected in randomized order for pneumatic or holmium: yag laser transurethral ureterolithotripsy (56 patients in each group). ultrasonog...

A patient with acute ureteral obstruction caused by buckshot is reported. Its occurrence is rare, and its management is similar to that of ureteral calculus.

introduction: surgical management of pediatric urinary calculi evolved dramatically over the past two decades. however, with the miniaturization of equipment and with improvisation of endourologic techniques, access to the entire pediatric urinary system is possible. ho: yag laser provides more maneuverability during transuretereal lithotripsy (tul) than the pneumatic system which uses a metal ...

Ureteral cavernous hemangiomas are an extremely rare, benign tumor. Most cavernous hemangiomas of ureter are diagnosed postoperatively by pathologic examination. A 39-year-old female patient presented with a bladder mass found incidentally by abdominal ultrasound. The patient underwent computed tomography, urine cytology, and cystoscopy. Cystoscopy showed 2 masses protruding from the right uret...

A 77-year-old man with urinary tuberculosis developed post renal anuria two days after starting an anti-tuberculosis drug regimen. He had bilateral hydronephrosis, and his right kidney was radiologically diagnosed to be non-functioning. A transurethral catheter was placed in the left ureter. No improvement in the ureteral stricture was noted during the initial three weeks of treatment; however,...

Iatrogenic ureteral injuries account for ∼75% of all ureteral injuries and occur primarily during urologic, gynecologic, general, and vascular surgery procedures. Ureteral injury during spine surgery is a rare complication with only occasional reports in the literature. In this case report, we present a case of unrecognized left ureteral injury during an open right lumbar discectomy with a dela...

conclusions we can remove the ureteral stent earlier after kidney transplantation with no increase in the prevalence of surgical complications. patients and methods all patients who underwent kidney transplantation from may 2011 until march 2012 in modarres hospital were included in this study. we classified the patients into three groups, based on time of stent removal (10, 20, and 30 days aft...

PURPOSE Malignant ureteral obstruction often necessitates chronic urinary diversion and is associated with high rates of failure with traditional ureteral stents. We evaluated the outcomes of a metallic stent placed for malignant ureteral obstruction and determined the impact of risk factors previously associated with increased failure rates of traditional stents. MATERIALS AND METHODS Patien...

PURPOSE To evaluate the patient and stone related factors which may influence the final outcome of SWL in the management of ureteral stones. MATERIALS AND METHODS Between October 2011 and October 2013, a total of 204 adult patients undergoing SWL for single ureteral stone sizing 5 to 15 mm were included into the study program. The impact of both patient (age, sex, BMI,) and stone related fact...

The ureter is possibly the least studied and most poorly understood organ of the urinary tract. The pathophysiologic basis underlying the use of α-blockers to improve ureteral stone passage or to treat ureteral stent symptoms is poorly understood. This, in part, may explain why clinical studies of medical expulsive therapy for ureteral stone passage are fraught with conflicting data. Methods to...
